STEAM PUMPING-ENGINE.

I SPECIFICATION forming part of Letters Patent No. 281,261, dated July 1'7, 1883. Application filed January 2, 1883. (No model.)

To all whom it may concern Be it known that I, HARVEY F. GASKILL, of Lockport, in Niagara county, New York, have invented certain Improvements in Steam Pumping-Engines, of which the following is a specification.

My invention is an improvement upon the engine of my Patent No. 263,694, dated September 5, 1882, and relates more especially to compound duplex pumpingengines, though parts of it may be used on pumping-engines of other kinds.

It consists in certain novel combinations of parts, among which the following may be noted as the more important, viz: two pumps ar ranged side by side; a crank-shaft mounted in bearings on the pumps; a fly-wheel on the crank-shaft and between the pumps; a highpressure and a low-pressure steam-cylinder arranged side by side and in line with the pumps; two beams intermediately located between the steam-cylinders and the pumps; air-pumps operated from the main beam-shaft; a condenser, &c.

The combinations which constitute my invention are specifically pointed out in the claims at the end hereof.

I am aware that it is common to arrange two engines side by side with pump-cylinders in line with the steam-cylinders; also, that it is common in compound engines of various forms to use a receiver for receiving the exhaust of the hi gh-pressure cylinders and supplying the low-pressure cylinders; also, that the use of cranks, fly-wheels, and beams is common, and these are not my invention.

In the drawings I have represented a comp ound condensing-engine containing my invention.

Figure 1 of the drawings is a side elevation of the engine from the side on which the airpumps and condenser are located. Fig. 2 is an end view of the same from the steam end of the engine.

Bis apump. The other pump does not show in the figures, being hidden by B and A.

G is a crankshaft mounted in bearingsf on the pumps.

F is a fly-wheel on the crank-shaft, and between the two pumps. The two cranks on the shaft are set at right angles, as shown in Fig. 1.

E is a high-pressure cylinder in line with pump B.

A is a low-pressure cylinder in line with the second pump.

N is the steam-pipe of cylinder E. M is its exhaust.

L is a receiver into which cylinder E exhausts.

N is a pipe conveying steam from the reeeiver to the low-pressure cylinder A.

K is a pipe through which cylinder A exhausts into the condenser C.

P is a standard to support bearings beam-shaft.

J is a beam.

g is a connecting-rod joining the upper end of beam J with crank G. The lower end of the beam is connected to the piston and pump-rod of cylinder E and pump B. A second beam is similarly arranged with reference to cylinder A and its pump and crank.

j is a secondary beam on the shaft of beam J.

B are the air-pumps. Their rods are connected to the ends of beam j, and they are operated by it. I have not shown these connections, as they would simply complicate the drawings.

P R is the foundation for the air-pumps and condenser.

O Q is the foundation for the main body of the engine.

What I claim isl. The combination of the two pumps, the crank-shaft mounted on the pumps, the flywheel on the crank-shaft, the high-pressure cylinder in line with one of the pumps, the lowpressure cylinder in line with the other pump, and connecting devices to constitute the whole into an operative machine, substantially as described.

2. The combination of the two pumps, the crank-shaft on the pumps, the fiy-wheel on the crank-shaft, the high and low pressure cylinders in line with the pumps, the beams, and connecting devices constituting the whole into an operative machine, substantially as de scribed.

3. The combination of the high and low pressure cylinders arranged side by side, the two pump-cylinders arranged side by side and in line with the steanrcylinders, the receiver, the

for the beams the crank-shaft and fly-wheel mounted in bearings on the pumps, and the cranks making an angle with each other, substantially as described.

4. The combination of the pumps, the crankshaft and fly-wheel mounted on the pumps, the steam cylinders, the beams, the secondary beam, the condenser and air-pumps, and conneeting devices constituting the whole into an operative machine, substantially as described. 10 HARVEY F. GASKILL.
